10. Finance and accounting

The statement of profit or loss summarises revenue and expenses over a period to show gross profit, operating profit and profit after relevant items. It is a period measure, not a cash account.

Interpretation requires consistent definitions, accruals and comparison with context. Profit can differ from cash because sales and costs may be recorded before money moves.

A sale on credit can increase revenue and profit while receivables rise; the business may still need cash to pay suppliers.

A positive profit figure does not guarantee liquidity, value creation or future performance.

The statement of financial position reports assets, liabilities and equity at a point in time. It shows what the business controls or is owed and how those resources are financed.

Current and non-current categories help assess liquidity, solvency and capital structure. The statement is a snapshot, so timing and valuation matter.

A business may own equipment financed by a loan; assets and liabilities rise together, while retained profit changes equity.

The statement does not show future cash flow or the market value of every resource, and “net assets” is not the same as cash.

Inventory is valued so that the statement reflects the cost of goods still held rather than goods already sold. The method and assumptions affect cost of sales, profit and current assets.

Obsolete, damaged or slow-moving stock may need a lower valuation. Consistency supports comparison, but the chosen method should reflect the information required.

If purchase prices rise, the cost assigned to units sold changes the reported gross profit and closing inventory even when physical stock is unchanged.

Inventory value is an accounting estimate, not automatically its selling price or cash value.

Depreciation spreads the depreciable cost of a non-current asset over the periods that benefit from its use. It reflects consumption of service potential; it is not a cash payment in the period recorded.

Method and useful-life estimates affect reported profit and asset value. A review is needed when usage, technology or residual value changes.

A machine bought for £10,000 with a four-year useful life may create an annual expense under straight-line assumptions, while cash was paid at purchase.

Depreciation does not set the market price of an asset and does not create a cash fund automatically.

The current ratio compares current assets with current liabilities; the acid-test ratio excludes inventory to focus on more liquid resources. Both are snapshots of short-term coverage.

A higher ratio may indicate protection but can also show idle cash or excess stock. Interpretation needs industry, timing, credit terms and trend.

A retailer with strong current assets mainly held as seasonal inventory may look liquid on the current ratio but weaker on the acid test.

No universal ratio proves safety; asset quality and when liabilities fall due matter.

Current ratio = current assets ÷ current liabilities. Acid-test ratio = (current assets − inventory) ÷ current liabilities. Write the formula before substituting values and use the same accounting definitions.

A ratio is meaningful only when the numerator and denominator refer to the same date and reporting basis. Compare trend and context rather than chasing a memorised target.

If current assets are 120, inventory 50 and current liabilities 80, the current ratio is 1.5 and the acid test is 0.875.

A mechanically correct calculation can still mislead if receivables are doubtful or liabilities are due immediately.

Gross profit margin relates gross profit to revenue; operating profit margin relates operating profit to revenue; return on capital employed compares operating profit with capital invested.

Ratios help compare performance over time or between firms, but differences may reflect price, product mix, accounting policy, asset age or risk—not just management quality.

A firm can raise gross margin through price or lower input cost while operating margin falls because marketing and administration rise.

A higher margin is not automatically better if it depends on unsustainable price, underinvestment or lower service quality.

Gross profit margin = gross profit ÷ revenue × 100. Operating profit margin = operating profit ÷ revenue × 100. ROCE = operating profit ÷ capital employed × 100.

Write the formula and definitions first, then compare with prior periods, competitors and the business model. A ratio is a signal, not an explanation.

If gross profit is 40 and revenue 200, gross margin is 20%; if operating profit is 20, operating margin is 10%. The gap invites investigation of overheads.

Do not compare ratios with different accounting definitions or treat a higher percentage as automatically better.

Efficiency ratios such as inventory turnover, receivables days, payables days and asset turnover relate resources or working capital to sales or cost. They help identify where cash or capacity is tied up.

Interpretation requires industry, seasonality, credit terms and trend. Improving one ratio can shift risk or quality elsewhere.

Faster inventory turnover may release cash, but if stockouts increase, the apparent improvement may damage service and sales.

A ratio does not reveal the mechanism alone; investigate policy, mix, timing and data quality.

Inventory turnover relates cost of sales to average inventory; receivables and payables days relate balances to the relevant sales or purchases flow. Use average balances when the question or data require them.

A formula is meaningful only when numerator, denominator, time period and unit are consistent. State whether a result is a percentage, a turnover or days.

Receivables days of 30 means the average balance represents roughly 30 days of credit sales under the model’s assumptions; it is not a direct measure of every customer’s payment.

A mechanically correct ratio can mislead if the denominator is mismatched or seasonal.

Gearing compares long-term debt or other fixed-return finance with capital employed or equity, depending on the definition used. It signals financial risk and dependence on lenders.

Debt can magnify returns when performance is strong, but interest and repayment remain when profits fall. Interpretation needs interest cover, cash flow, asset security and industry context.

A business funding expansion mostly with debt may grow faster, but a demand shock can leave it unable to service repayments even if the assets remain valuable.

High gearing is not automatically bad and low gearing is not automatically safe; risk depends on stability and cash generation.

A gearing formula may use long-term loans ÷ capital employed × 100 or another syllabus-defined basis. Write the exact definition before substituting values and label the result.

Different definitions produce different percentages, so comparisons require the same formula, date and accounting basis.

If long-term debt is 60 and capital employed 200, the stated definition gives 30%; changing the denominator to equity would answer a different question.

A ratio is not self-explanatory: formula, period and denominator must accompany interpretation.

Investment ratios such as earnings per share, dividend yield, dividend cover and price-earnings ratio relate shareholder returns or market price to profit and dividends.

They can support comparison, but market expectations, risk, growth prospects, payout policy and one-off earnings affect interpretation.

A high P/E may reflect expected growth rather than overpricing; a high dividend yield may reflect a falling share price or an unsustainably high payout.

Ratios do not predict future returns and should not be read without the underlying earnings and dividend context.

Earnings per share divides profit available to ordinary shareholders by the number of ordinary shares. Dividend yield compares dividend per share with market price; dividend cover relates earnings to dividends.

Write the exact definition before calculating because accounting treatment, share count and timing affect the result.

A high dividend yield can arise from a generous payout or a falling share price; the same percentage can signal opportunity or risk depending on earnings and expectations.

A formula output is not an investment recommendation and cannot predict future price or dividends.

Investment appraisal evaluates whether a project’s expected benefits justify its cost and risk. It should consider cash flows, timing, capacity, strategy and alternatives.

Different methods simplify different aspects. The decision depends on assumptions about demand, costs, asset life, discount rate and the opportunity cost of funds.

A new machine may reduce unit cost but require training and downtime; its value depends on the incremental cash flow and strategic fit, not price alone.

A positive calculation does not remove implementation risk or guarantee the forecast.

Payback measures how long a project takes to recover its initial cash outlay. Accounting rate of return compares average accounting profit with an investment basis. Payback emphasises liquidity; ARR emphasises reported profitability.

Payback ignores cash flows after recovery and often ignores time value; ARR depends on accounting profit and depreciation assumptions. Use each only for the decision purpose it can support.

Project A may recover cash quickly but earn little later, while Project B may have a slower payback but stronger long-term returns.

A shorter payback is not automatically the most profitable project.

Net present value subtracts the initial investment from the present value of expected future cash inflows and outflows, using a discount rate that reflects time and risk.

Money received later is not equivalent to money received now. NPV recognises timing and can compare projects whose cash flows arrive at different times, provided assumptions are credible.

A project with a large cash inflow in year five may have a lower present value than its undiscounted total suggests; changing the discount rate can change the ranking.

NPV is only as reliable as the cash-flow and discount-rate assumptions, and a positive NPV is not a guarantee.

Choose an investment by combining appraisal results with strategic fit, risk, capacity, capability, stakeholder effects and the quality of evidence.

A project can score well financially yet conflict with regulation, skills or brand; another can have a lower immediate return but build essential capability.

A renewable-energy investment may have a longer payback but reduce exposure to volatile energy prices and support a strategic commitment.

There is no single metric that decides every investment; state assumptions and trade-offs explicitly.

Accounting data such as profit, cash flow, assets, costs and ratios provides evidence for strategic choices. It should be combined with market, operational and stakeholder information.

Historical accounts describe what happened under past conditions; strategy concerns future choices. Definitions, one-off items and accounting policy can affect comparability.

A falling margin may prompt a pricing review, but managers should also check product mix, customer retention, capacity and competitor moves before changing strategy.

Financial data is evidence, not the whole explanation; a ratio cannot replace causal investigation.

Ratio analysis compares profitability, liquidity, efficiency, gearing or investment indicators across time or firms. It helps identify questions about performance and risk.

Interpret ratios with business model, industry, trend, accounting basis, seasonality and strategy. A movement can be a symptom of a deliberate choice rather than failure.

Faster inventory turnover may release cash but reduce availability; a lower margin may fund a launch that builds long-term market share.

Ratios do not prove cause or future success, and benchmarks are meaningful only when definitions and context match.
